Memory leaks in SessionDetailFragment onwards

[surajsau]

Overview:
When session details screen is opened, frequent memory leaks are captured by LeakCanary

Steps To Reproduce:
launch app
click on any session
scroll up and down or click on feedback and scroll between the views
Leak Canary records memory leaks very frequently.

Expected behavior:
Memory leaks must be reduced

Env:

Device: [e.g. Pixel3]
OS: [e.g. 9.0]
App Version or the branch [master]

Additional context:
It's happening because of ViewDataBinding. It isn't being cleared in onDestroyView()
We can take out binding as variable in the base DaggerFragment and set it to null in onDestroyView()

@takahirom I can take it up and fix it if needed.
